HISTORY
& OWNERSHIP
Diesel Truck Driver Training School was founded when Robert Klabacka started teaching the trades in 1959 making us one of America’s oldest and largest CDL training schools. Robert later passed the reins onto his sons who continue to maintain the same high standards and superior quality people have come to expect from Diesel Truck Driver Training School.
